Problems solved by technology

[0002] Compound fertilizer is the fertilizer that agricultural crops rely on after growing. Especially in recent years, the high-tower granulated compound fertilizer featuring high nitrogen and high potassium has been favored by people, because the effective nutrients in the fertilizer have a considerable effect on the soil. Part of the nutrients are decomposed or lost or volatilized, and cannot exert its proper fattening effect. According to statistics, the utilization rate of commonly us

Embodiment 1

[0038] Embodiment 1, a kind of polypeptide compound fertilizer, is added with polyaspartic acid or its salt in the described compound fertilizer, as shown in the figure, described polyaspartic acid or its salt molecular weight is 1500-5000, from this structure It can be seen that it has a very strong chelating ability for metal ions, and because it has the peptide bond properties of proteins, it not only has a strong adsorption ability for cations, but also has a strong adsorption ability for anions, and it is non-toxic, harmless, and has no residue. Biodegradable.

[0039] It can also be seen from the structural formula that not only the internal gene -COOH, but also the gene groups -COOH and -NH at the end 2 It can still chelate various anions and cations, which also lays the foundation for the strong adsorption capacity of the polymeric amino acid, and polyaspartic acid or its salt has good water solubility, easy to decompose and absorb, and polyaspartic acid or The salt a...

Embodiment 2

[0051] Embodiment 2, a kind of polypeptide compound fertilizer, is added with polyaspartic acid or its salt in the described compound fertilizer, as shown in the figure, described polyaspartic acid or its salt molecular weight is 1500-5000, from this structure It can be seen that it has a very strong chelating ability for metal ions, and because it has the peptide bond properties of proteins, it not only has a strong adsorption ability for cations, but also has a strong adsorption ability for anions, and it is non-toxic, harmless, and has no residue. Biodegradable.

[0052] It can also be seen from the structural formula that not only the internal gene -COOH, but also the gene groups -COOH and -NH at the end 2 It can still chelate various anions and cations, which also lays the foundation for the strong adsorption capacity of the polymeric amino acid, and polyaspartic acid or its salt has good water solubility, easy to decompose and absorb, and polyaspartic acid or The salt a...

Abstract

A composite polypeptite fertilizer for promoting growth, and improving crop quality and soil is prepared from a composite fertilizer and polyaminosuccinic acid or its salt through preparing composite fertilizer, preparing the aqueous solution of polyaminosuccinic acid or its salt, mixing and granulating.

Description

technical field [0001] The invention relates to a compound fertilizer used in agriculture and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] Compound fertilizer is the fertilizer that agricultural crops rely on after growing. Especially in recent years, the high-tower granulated compound fertilizer featuring high nitrogen and high potassium has been favored by people, because the effective nutrients in the fertilizer have a considerable effect on the soil. Part of the nutrients are decomposed or lost or volatilized, and cannot exert its proper fattening effect. According to statistics, the utilization rate of commonly used compound fertilizers is only 15%-30%. This method of application leads to waste of resources. Increasing the amount of fertilization in order to increase production has little effect on crops, which can only lead to waste of resources, increased costs, and environmental pollution. Moreover, the prod...
